6. system Description
6.1. Designated application area
The electromotive rotary actuator Type 3005 (designated below as
rotary actuator) was developed to control ball valves or flap valves with
a quarter turn. Optionally the actuator is also available at a rotation
angle of 180° and 270°.
6.2. General Description
On account of its modular design the basic device can be expanded
with many options.
Options for expanding the basic device can be found in
chapter "6.3. Options".
The rotary actuator is a compact and powerful actuator system which
ensures a long service life. The rotary actuator is designed for direct
or alternating current at varying power and for torques from 25 to
1000 Nm (actuator with analogue signal 25 - 300 Nm).
The utilised materials guarantee maintenance-free operation and
ensure a low thermal load. All standard version rotary actuator feature
manual emergency actuation and two additional limit switches and
are tested by the manufacturer. The limit switches have been set to
0 - 90° swivel operation.
The electromotive rotary actuator is available as an On/Off or variable
speed actuator. It can be combined with the following components:
• Stainless steel ball valve with two-part body (Type 2651)
• Stainless steel ball valve with three-part body (Type 2654)
• Plastic ball valve (Type 2657)
Type 3005
• Metal flap valve (Type 2671)
• Plastic flap valve (Type 2674)
The actuator direction cannot be reversed in the same operating
process. The rotary actuator does not reverse automatically.
Mechanical operation, without switching over the motor, is also pos-
sible via the handwheel on the rotary actuator. In electrical mode the
handwheel is not rotated with the actuator.
